Ever wish ChatGPT could write exactly like you? Guess what — it can! All you need is a personal AI style guide. It’s like giving GPT your favorite pen so it writes just the way you do. Let’s walk through how to make one. It’s easier (and more fun) than you think!

Why a Style Guide Matters

ChatGPT is super smart, but it doesn’t automatically know your style. Do you like emojis? Do you keep things formal? Or do you crack jokes every other sentence? A style guide helps ChatGPT capture all those little things that make your writing you.

Think of it like dressing up. The guide tells GPT what outfit to wear—whether it’s jeans and sneakers or a full-on tuxedo.

Step 1: Collect Your Samples

Start by gathering things you’ve written. Look for:

  • Emails
  • Blog posts
  • Social media captions
  • Text messages (really!)

Your own words are gold. Highlight the parts where you sound most like yourself. Are you serious? Silly? Sarcastic?

Step 2: Define Your Voice

This is the fun part. You get to tell GPT who you are as a writer. Use simple categories like these:

  • Tone: Friendly, Professional, Witty, Casual, Academic
  • Sentence Length: Short and punchy? Or long and thoughtful?
  • Vocabulary: Everyday words or complex terms?
  • Grammar: Do you follow the rules or break them for fun?
  • Emojis: Every sentence? Never?

Here’s an example:

“My writing is casual and playful. I like short sentences and rhetorical questions. I use emojis, but not too many. I sometimes start sentences with ‘And’ or ‘But’. It should feel like a fun chat over coffee.”

Step 3: Create a Style Guide Template

Make a simple format. You can copy this and customize it:

Name: Coffee Shop Chat Vibes  
Tone: Casual, friendly  
Sentence Length: Mostly short  
Grammar Rules: Flexible  
Common Phrases: “Let’s be honest”, “Here’s the thing”  
Things to Avoid: Overly formal words, too many stats  
Emoji Use: Light use – mostly for tone 😊

This template helps ChatGPT stay on-brand — your brand.

Step 4: Feed it to ChatGPT

Now the magic happens. Start a new chat and say:

“Please write all responses in my personal writing style. Here’s my style guide:”

Then paste in your guide. ChatGPT will follow it like a recipe.

Step 5: Test, Tweak, Repeat

Ask GPT to write a few things using your style:

  • A friendly email
  • A tweet
  • A blog intro

If it sounds off, just adjust your guide. It doesn’t have to be perfect the first time. Think of it like training your AI pen pal.

Cool Extra Tips

  • Version it: You can make different guides for different moods — like “Excited Launch Day Vibe” or “Serious Business Pitch”
  • Quote Yourself: Add actual phrases you’ve used so GPT can mimic your voice better
  • Highlight No-Nos: If you hate certain phrases, add them to a “never use” list

Final Words — In Your Words!

Creating a style guide doesn’t have to be boring. You’re basically teaching a robot to sound like you. That’s kind of awesome, right?

In a world full of AI, your voice is your superpower.

So make your style guide, share it with ChatGPT, and let the magic begin!
